When you turn the coarse adjustment knob of a microscope, it moves the stage up or down to bring the specimen into rough focus. This adjustment is used to quickly change the focus of the image.

What part of the microscope should you used to focus the image when using high power objective lens?

First of all, one should never call it high power, it is morecommonly called the "high objective", yet that is not what this question is asking. To answer the question: You use the fine adjustment knob. This knob should be located near the coarse adjustment knob, on the opposite side of the microscope (at the same height as the coarse adjustment knob), or even as a separate knob protruding from the coarse adjustment knob. The fine adjustment knob is smaller in size. You should never, ever use the coarse adjustment knob under the high objective, you could scratch the microscope slide, cover slip, high objective lens, or in a worst case scenario break the high objective lens.


Why is only fine adjustment used for high power?

Because if you use coarse adjustment, the body tube of the microscope (the part that moves up and down when you turn the knobs) will hit the microscope slide and cause the slide to break/crack. It moves the tube very quickly . You also run the risk of damaging the high power lens when it hits the slide. The fine adjustment only moves the tube a teeny tiny bit and very slowly so you don't have a great of a risk of damaging the slide or lens. The fine adjustment also helps to focus slowly so you don't miss the object you're trying to see.
